Embodiment

Advantage of the present utility model, feature and the method for realizing them, by referring to accompanying drawing and are detailed below Embodiment can become clear and definite.But the utility model is not limited by embodiment as disclosed below, but it can realize For mutually different various forms, and the present embodiment is intended merely to complete disclosure the utility model, and be in order that this The personnel with usual knowledge completely understand the utility model scope and provided, this practicality in utility model art Depending on new by the scope of claim.The overall identical inscape of identical reference numbers of specification.

When illustrating embodiment of the present utility model, if known function or related the illustrating of composition have been judged as In the case of purport of the present utility model unnecessarily may being obscured, detailed description thereof will be omitted.And term described later Allow for the function in embodiment of the present utility model and define, its may according to user, transport user intention or Convention and it is different.Therefore, depending on its definition should be based on the entire content of this specification.

Hereinafter, referring to the drawings to being described in detail according to the starter-generator of the utility model embodiment.

Fig. 1 is to show the assembled state figure according to the starter-generator of the utility model embodiment, and Fig. 2 is shown according to this The decomposing state figure of the starter-generator of utility model embodiment, Fig. 3 and Fig. 4 are in the starting according to the utility model embodiment The figure of the connecting portion of motor and inverter is observed in generator from different perspectives.

Referring to figs. 1 to 4, motor 100 and inverter 200 are included according to the starter-generator 1 of the utility model embodiment, and And in order to connect motor 100 and inverter 200, there is connecting portion 110 on motor 100, and be provided with inverter 200 The bus assembly 300 being connected with connecting portion 110.

The starter-generator 1 is connected with engine (not shown) by belt (belt), and is passed by belt to engine The driving force of motor 100 is passed, so as to assist to start and drive, or the engine driving force of transmission is received, so as to enter as generator Row operation.

Now, the motor 100 and inverter 200 for constituting the starter-generator 1 play respective effect, the motor 100 actually play a part of produces driving force or receive driving force and produce electric power.

Also, the inverter 200 is in the case of the produces driving force of motor 100, the DC electricity supplied from 48V battery receptacles Power, so that the AC electric power of motor 100 is changed, so that motor 100, in the case where motor 100 receives driving force, electricity The AC power converters of machine 100 are DC electric power, so as to be charged to 48V batteries.

In starter-generator 1, the operation of motor 100 and inverter 200 is known item, is omitted to the specific of its Explanation.

In addition, for the mutual operation of the motor 100 and inverter 200, the electricity between motor 100 and inverter 200 Connection is necessary, for the electrical connection between motor 100 and inverter 200, according to embodiment of the present utility model, motor 100 With connecting portion 110, inverter 200 is provided with the bus assembly 300 being connected with connecting portion 110.

The connecting portion 110 protrudes, inside motor 100 to be combined with bus assembly 300 from the side of motor 100 Draw, and may be configured as being provided with access terminal 115 in the end for the line 113 for being covered with insulator 111.

Now, the access terminal 115 includes：Combined hole, it is used to be combined with line 113；Board, it is used for and bus Component 300 is combined.In other words, it is described access terminal 115 combined hole combine wired 113, and it is described access terminal 115 knot Plywood is combined with bus assembly 300.

In addition, the bus assembly 300 protrudes from the side of inverter 200, so that the knot of connecting portion 110 with motor 100 Close.Thus, combined by bus assembly 300 and joint portion 110, motor 100 and inverter 200 are electrically connected.

Now, the bus assembly 300 is separately fabricated and be arranged at inverter 200, and inverter 200 is provided with for combining The opening portion of bus assembly 300.

Fig. 5 is the bus assembly for showing to be arranged on the inverter according to the starter-generator of the utility model embodiment Figure, Fig. 6 is the bus of bus assembly for showing to be arranged on the inverter according to the starter-generator of the utility model embodiment Figure.

Reference picture 5 and Fig. 6, specific observation bus assembly 300, the bus assembly 300 include bus 300 and main body 330, And packing ring 330 can be further comprised.

The bus 310 is formed as the path for electrically connecting by metal material, and one end of the bus 310 111 are connected with the line drawn from the inside of inverter 300, and the other end 113 of the bus 310 connects with the connecting portion 110 of motor Connect.

Now, it is preferable that the bus 310 is formed for ease of the connection with the connecting portion 110 of motor 100 and firmly connection Structure.

Thus, the other end 113 for the bus 310 being connected with the connecting portion 110 of the motor 100 is formed asShape. In other words, the other end 313 of the bus 310 includes：First plate and second plate 313a, 313b, it is set to refer to interval The state for determining space 313d is faced each other；3rd plate 313c, it connects with the first plate and second plate 313a, 313b one end respectively Connect, and the space 313d between the first plate and second plate 313a, 313b is combined with the connecting portion 110 of motor 100.

In addition, because being formed with space 313d between first plate and second plate 313a, 313b, by motor In the state of the 100 insertion space 313d of connecting portion 110, can from outside to inside it be pushed away in the first plate and second plate 313a, 313b Welding is realized under state, as a result, connecting portion 110 can be firmly attached to bus 310.

Thus, even if engine sharp pounding, the connecting portion of connecting portion 110 and bus 310 also will not delamination, and energy Enough improve durability.

In addition, main body 330 may be damaged when being welded to connecting portion 110 and bus 310, it is therefore preferred that applying big Electric current to connecting portion 110 and bus 310 so as to weld within a short period of time.

Also, one end 311 of the bus 310 with the knot drawn from the inside of inverter 300 for ease of closing, described One end 311 of bus 310 is formed with combined hole 311a.

The main body 330 is placed around the side of bus 310, and is approximately at the center of bus 310, so that bus 310 one end 311 and the other end 313 are not surrounded by main body 330 and exposed to outside.

The main body 330 when bus assembly 300 is incorporated into inverter 200 as the structure contacted with inverter 200, by Insulating materials is formed.

Now, can between bus 310 and main body 330 in order to improve the air tightness between the bus 310 and main body 330 It is coated with encapsulant.

In addition, the packing ring 350 in order that bus assembly 300 can be to keep the combinations of states of air-tightness in inverter 200, the outside of main body 330 is incorporated into ring-type.

In other words, the packing ring 350 in order to improve the air-tightness between the bus assembly 300 and inverter 200 and Main body 330 is arranged at, for ease of assembling, it is preferable that the packing ring is formed at main body 330 with low-durometer material, and can Main body 330 is integrally formed at by sticker.

In addition, by embodiment to being illustrated according to starter-generator of the present utility model, but the utility model Scope be not limited to specific embodiment, it is self-evident in the personnel with common knowledge on the utility model In the range of can by carry out it is various replace, modifications and changes are implemented.

Thus, the embodiment and accompanying drawing described in the utility model be illustrate rather than for limit it is of the present utility model Technological thought, and limit not by the embodiment and accompanying drawing the scope of technological thought of the present utility model.This practicality New protection domain should be explained by right, and whole technological thoughts in the scope equal with it should be solved It is interpreted as being contained in right of the present utility model.
